12 | Module Name:\r | |
13 | \r | |
14 | WinNtBusDriver.h\r | |
15 | \r | |
16 | Abstract:\r | |
17 | \r | |
18 | This following section documents the envirnoment variables for the Win NT \r | |
19 | build. These variables are used to define the (virtual) hardware \r | |
20 | configuration of the NT environment\r | |
21 | \r | |
22 | A ! can be used to seperate multiple instances in a variable. Each \r | |
23 | instance represents a seperate hardware device. \r | |
24 | \r | |
25 | EFI_WIN_NT_PHYSICAL_DISKS - maps to drives on your system\r | |
26 | EFI_WIN_NT_VIRTUAL_DISKS - maps to a device emulated by a file\r | |
27 | EFI_WIN_NT_FILE_SYSTEM - mouts a directory as a file system\r | |
28 | EFI_WIN_NT_CONSOLE - make a logical comand line window (only one!)\r | |
29 | EFI_WIN_NT_UGA - Builds UGA Windows of Width and Height\r | |
30 | EFI_WIN_NT_SERIAL_PORT - maps physical serial ports\r | |
31 | EFI_WIN_NT_PASS_THRU - associates a device with our PCI support\r | |
32 | \r | |
33 | <F>ixed - Fixed disk like a hard drive.\r | |
34 | <R>emovable - Removable media like a floppy or CD-ROM.\r | |
35 | Read <O>nly - Write protected device.\r | |
36 | Read <W>rite - Read write device.\r | |
37 | <block count> - Decimal number of blocks a device supports.\r | |
38 | <block size> - Decimal number of bytes per block.\r | |
39 | \r | |
40 | NT envirnonment variable contents. '<' and '>' are not part of the variable, \r | |
41 | they are just used to make this help more readable. There should be no \r | |
42 | spaces between the ';'. Extra spaces will break the variable. A '!' is \r | |
43 | used to seperate multiple devices in a variable.\r | |
44 | \r | |
45 | EFI_WIN_NT_VIRTUAL_DISKS = \r | |
46 | <F | R><O | W>;<block count>;<block size>[!...]\r | |
47 | \r | |
48 | EFI_WIN_NT_PHYSICAL_DISKS =\r | |
49 | <drive letter>:<F | R><O | W>;<block count>;<block size>[!...]\r | |
50 | \r | |
51 | Virtual Disks: These devices use a file to emulate a hard disk or removable\r | |
52 | media device. \r | |
53 | \r | |
54 | Thus a 20 MB emulated hard drive would look like:\r | |
55 | EFI_WIN_NT_VIRTUAL_DISKS=FW;40960;512\r | |
56 | \r | |
57 | A 1.44MB emulated floppy with a block size of 1024 would look like:\r | |
58 | EFI_WIN_NT_VIRTUAL_DISKS=RW;1440;1024\r | |
59 | \r | |
60 | Physical Disks: These devices use NT to open a real device in your system\r | |
61 | \r | |
62 | Thus a 120 MB floppy would look like:\r | |
63 | EFI_WIN_NT_PHYSICAL_DISKS=B:RW;245760;512\r | |
64 | \r | |
65 | Thus a standard CD-ROM floppy would look like:\r | |
66 | EFI_WIN_NT_PHYSICAL_DISKS=Z:RO;307200;2048\r | |
67 | \r | |
68 | EFI_WIN_NT_FILE_SYSTEM = \r | |
69 | <directory path>[!...]\r | |
70 | \r | |
71 | Mounting the two directories C:\FOO and C:\BAR would look like:\r | |
72 | EFI_WIN_NT_FILE_SYSTEM=c:\foo!c:\bar\r | |
73 | \r | |
74 | EFI_WIN_NT_CONSOLE = \r | |
75 | <window title>\r | |
76 | \r | |
77 | Declaring a text console window with the title "My EFI Console" woild look like:\r | |
78 | EFI_WIN_NT_CONSOLE=My EFI Console\r | |
79 | \r | |
80 | EFI_WIN_NT_UGA = \r | |
81 | <width> <height>[!...]\r | |
82 | \r | |
83 | Declaring a two UGA windows with resolutions of 800x600 and 1024x768 would look like:\r | |
84 | Example : EFI_WIN_NT_UGA=800 600!1024 768\r | |
85 | \r | |
86 | EFI_WIN_NT_SERIAL_PORT = \r | |
87 | <port name>[!...]\r | |
88 | \r | |
89 | Declaring two serial ports on COM1 and COM2 would look like:\r | |
90 | Example : EFI_WIN_NT_SERIAL_PORT=COM1!COM2\r | |
91 | \r | |
92 | EFI_WIN_NT_PASS_THROUGH =\r | |
93 | <BaseAddress>;<Bus#>;<Device#>;<Function#>\r | |
94 | \r | |
95 | Declaring a base address of 0xE0000000 (used for PCI Express devices)\r | |
96 | and having NT32 talk to a device located at bus 0, device 1, function 0:\r | |
97 | Example : EFI_WIN_NT_PASS_THROUGH=E000000;0;1;0\r | |
